Each week this recipe reads the Stripe ledger for the ISO week — charges, payouts, refunds, disputes, and fee lines by class — and computes subscription movement: new, expanded, contracted, and churned MRR with subscriber counts, not just dollar totals. It loads last week's snapshot from memory and explains every top change with a one-line attribution to the actual transactions ("inflow +$4,210, driven by the Acme annual renewal plus three new monthly subs") — an unattributed delta is labeled as such rather than narrated plausibly. Anomalies are flagged against last week and the trailing 4-week average with their dollar impact, ranked by materiality. The brief lands in-hub as the primary deliverable, with an optional email version staged as a Gmail draft — never sent. Reruns upsert the same week's brief, labeling partial-week snapshots as partial, and store the snapshot for next week's comparison.
